COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Brief name: Assistive technologies system

Forty intervention patients will be provided with an integrated assistive technologies system comprised of four components:
1. SofiHub reminder hub, which can be remotely programmed by the participant and carers to provide personalised, timed audio reminders for participants to take medications or engage in routine activities of daily living.
2. Up to eight SofiHub infrared sensors, which are placed at strategic locations around the house to identify the location of the participant within their home and their use of medications. These sensors only detect movement and do not record audio or video data.
3. A tablet-based communication system, which allows participants to make immediate video or voice calls to a caregiver, and displays text reminders and messages from carers.
4. A wearable device with an emergency alarm button, which monitors energy expenditure and detects falls, stumbles and near falls.

The assistive technologies system will be installed in participant homes by a technical team from the University of NSW. The study coordinator will be present at installation to assist the person responsible/carer and participant to understand the use and objectives of each technology. Data collection from the assistive technology system is automated and will be displayed on an online portal, accessible to the study coordinator. The intervention will be provided for six months.

The technologies system will provide personalised reminders and alerts to the patients and care network. A 30 minute face-to-face consultation with the participant and his/her carers will be conducted by the study coordinator to determine the specific content and frequency of these reminders, prior to system installation. These will be programmed into the technologies by the study coordinator and ready for use at the time of installation.

Concealed randomisation will be performed on a computer with the randomisation facilities within the scientific programming package MATLAB by someone external to the project team.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The 'datasample' function on MATLAB will be used to randomly allocate enrolled participants to the intervention or control group.

Efficacy
Statistical methods / analysis
A power analysis with 5% significance levels was undertaken using data from previous work and similar studies to determine a total of 80 participants (40 per group) will provide 80% power to detect a significant 30% change in the primary outcome measure.

MATLAB and SPSS will be used for all data analysis. All data collected will be tested for normality using the single sample Kolmogorov-Smirnov goodness of fit hypothesis test. Categorical variables will be tested with a one sample t-test with a null hypothesis of 'mean is zero'. Paired sample t-tests will be used to test before and after differences in paired observations. The Wilcoxon rank sum test for equal medians will be used for data that are non-normally distributed.

Primary and secondary outcomes will be analysed primarily using before and after changes in the scored questionnaire instruments. These will be correlated against the longitudinal sensor data collected automatically by the technology system. Interactions will be analysed using multivariate analysis methods.

Descriptive data models will be used including basic statistics, clustering methods and principal component analysis (PCA). Regression and predictive models include multiple linear regression, principal component regression or partial least squares regression. We will explore classification models such as support vector machine, linear discriminant analysis and partial least squares-discriminant analysis. Some or all of these methods may be applied to the data depending on the level of significance of outcomes achieved.

Summary
Brief summary
In this study, we will randomly assign 80 people living with dementia into two groups, an intervention or a control group. Forty participants in the intervention group will receive a range of low cost, adaptable, user-centric technologies installed in their homes, while 40 participants in the control group will continue to receive usual care. These technologies include a wearable falls detector, a communication tablet, personalised reminders for medication taking and other routine activities, and motion sensors installed around the home. The study aims to see whether these technologies will help people living with dementia better manage their routine activities of daily living, and examine the impact of these technologies on the people living with dementia and their informal carers. The intervention will be provided for six months.
